Also my add-ons to those lists, Resident Evil's 1-3,(No. 2 being my personal fave), Gran Turismo for reasons already explained, FFVIII, Suikoden-an under rated RPG-not on the scale of FFVII's brilliance but it has some innovative aspects the further you delve into it, surprised noone mentioned Bust a Move(Puzzle Bobble), and Tekken 2, & Shane Warne's Cricket (Think it was originally Brian Lara's Cricket O/S), also enjoyed Blood Omen Legacy of Kain, & was introduced to Broken Sword via the PS1.

BTW-still have my original non-analogue sony pads from my PS1 from about 5-6 yrs ago, still going strong!
